I like the idea they are coming during CI so this is a time when you can play with the children. Scaffold the learning and work with them. It also depends on what your CI looks like but for me it's about the quality of the adult interaction. Don't ask a question if you already know the answer, play alongside and talk about what you are doing, get involved. I don't teach anymore but when I did I used the High/Scope approach and you can see a great 3min clip here of adult interaction during play if you are interested. http://www.highscope.org/Content.asp?ContentId=381 Click on the grid for adult interactions then click on eating snakes! It's great!
